The Billboard 200 chart ranks the week’s most popular albums based on their overall consumption. That overall unit figure combines pure album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA).

Now, let’s take a closer look at some of the action on the latest Billboard 200 chart:

— Melissa Etheridge, Memphis Rock and Soul - No. 34 — Melissa Etheridge keeps up her hot streak in the top 40 of the Billboard 200, as her latest album, Memphis Rock and Soul, debuts at No. 34. It’s her 14th top 40-charting set — her only album to miss the region was the 2008 holiday effort, A New Thought for Christmas (No. 113 peak).

Etheridge made her Billboard 200 debut nearly 30 years ago, on the Jun 18, 1988-dated list, with her self-titled album. It eventually peaked at No. 22 the following year.

Etheridge’s new blues/rock album is a covers set of tunes associated with the Stax label, and also debuts at No. 9 on Top Rock Albums and No. 1 on the Blues Albums chart — Etheridge’s first leader on the latter tally.

— Daya, Sit Still, Look Pretty - No. 36 — After peaking at No. 61 with her self-titled debut EP, the rising star bows at No. 36 with her first full-length album, Sit Still, Look Pretty. The set starts with 13,000 equivalent album units earned, of which 6,000 were in traditional album sales. The new album includes her breakthrough single “Hideaway,” which peaked at No. 23 on the Billboard Hot 100, and the title cut, which has so far reached No. 28 on the list. (The album does not feature her monster hit with The Chainsmokers, “Don’t Let Me Down,” which peaked at No. 3. The track isn’t actually on any album yet.)

— Barry Gibb, In the Now - No. 63 — Barry Gibb’s second solo album begins at No. 63, and is his first collection of all new material since the final Bee Gees studio album, 2001’s This Is Where I Came In. Gibb’s first solo set, Now Voyager, hit No. 72 in 1984.

— Bruno Mars, Doo-Wops & Hooligans - No. 116 — Bruno Mars’ debut album, Doo-Wops & Hooligans, jumps back onto the list at No. 116 (6,000 units; up 40 percent) following the release of his new single “24K Magic.” It’s the highest rank for the album since the Feb. 27-dated chart, when it placed at No. 107 (up from No. 174 the week previous), following his performance during the Super Bowl halftime show. Mars’ second album, Unorthodox Jukebox, also bounds back onto the new Billboard 200, at No. 147 (5,000 units; up 52 percent).

— Van Halen, 5150 - No. 132 —5150 (5,000 units earned in the week ending Oct. 13; up 149 percent) returns after Google Play discounted the set to 99 cents. The set has been absent from the chart since June of 1987.

The album was Van Halen’s first No. 1, and topped the list for three weeks a little more than 30 years ago (April 26-May 10, 1986). The band followed up 5150 with four more chart toppers: OU810 (1988), For Unlawful Carnal Knowledge (1991), Balance (1995) and Best of Volume 1 (1996).

— Garth Brooks, The Ultimate Hits - No. 150 — The superstar’s 2007 hits album returns to the list for the first time in over a year, following its reissue on Oct. 7. The set debuted and peaked at No. 3 on the Nov. 24, 2007-dated chart. Brooks most recently hit the chart with a new album nearly two years ago, when Man Against Machine bowed and peaked at No. 4 on Nov. 29, 2014.
